Ditto.

Now it's rarely hot where I ride, so I don't need them but that was all we used when I lived in NC. A regular bottle would leave my frozen water HOT by the time I finished it - the polar bottle - still cool.

It would stay frozen way longer if you fill it half full and leave it on it's side in the freezer overnight. The solid ice mass melts much slower than cubes (less surface area).

I also agree about wearing a wet buff on your head under your helmet. It holds water better than hair, so it stays cool. Just squeeze some extra water into it when you stop to keep it wet.
